Q121.
_____ is assembling a cohesive set of data and functions to define an object.

a.

Message passing

b.

Encapsulation

c.

Polymorphism

d.

Inheritance

Discuss
Answer: (b).Encapsulation Explanation:The first step in the development of object oriented models is the identification of object classes. This is accomplished by encapsulation. Encapsulation is assembling a cohesive set of data and functions to define an object.
Q122.
_____ facilitates interconnection across physical boundaries of various devices.

a.

Polymorphism

b.

Message passing

c.

Filtering

d.

Modulation

Discuss
Answer: (b).Message passing Explanation:Message passing permits conceptual integration of software components. It also facilitates interconnection across physical boundaries of various devices used for development such as FPGA.
Q123.
Syntax and semantics of messages are compiled in a ______

a.

data dictionary

b.

data directory

c.

method dictionary

d.

method directory

Discuss
Answer: (a).data dictionary Explanation:Syntax and semantics of messages are compiled in a data dictionary. The proper format (syntax) and meaning (semantics) of messages are necessary for successful integration of software and hardware.
Q124.
____ enables the definition of reusable classes.

a.

Polymorphism

b.

Inheritance

c.

Object

d.

Overloading

Discuss
Answer: (b).Inheritance Explanation:Property inheritance allows the definition of reusable classes of software objects. This allows the synthesis of task-specific objects. FIR is an example for a generic software object and mark filter is an example for task-specific software object.
Q125.
_____ is the ability of a software object to exhibit different behaviours in accordance to the current context.

a.

Polymorphism

b.

Inheritance

c.

Object

d.

Class

Discuss
Answer: (a).Polymorphism Explanation:Polymorphism is the ability of a software object to exhibit different behaviours in accordance to the current context. Polymorphism adds a degree of independence to underlying data structure. It also eliminates duplicate code.
Q126.
Abstract external objects are called ____ in UML terminology.

a.

actions

b.

actors

c.

actuators

d.

actuation

Discuss
Answer: (b).actors Explanation:The UML is a general purpose, modeling language intended to provide a standard way for defining the design of a system. Abstract external objects are called actors in UML terminology. Actors have properties and behavior that shape the system design.
Q127.
____ is an isochronous stream.

a.

Control flow

b.

Data flow

c.

Signal flow

d.

Control flow and data flow

Discuss
Answer: (c).Signal flow Explanation:Signal flow is an isochronous stream. Data flow contains near-real-time data packets. Control flow shifts control of processor towards software objects. The context diagram identifies all signal flows, data flows, and control flows with external entities.
Q128.
_____ must invoke an appropriate response from the software.

a.

Object

b.

Call

c.

Event

d.

Prompt

Discuss
Answer: (c).Event Explanation:External event is a stimulus that invokes an appropriate response from the system. Each event might invoke more than one system response. A comprehensive collection of events is called an event-response list.
Q129.
Techniques such as positive acknowledgement and timeouts must be employed to prevent ____ of critical event.

a.

delay

b.

continuous selection

c.

retransmission

d.

suspension

Discuss
Answer: (d).suspension Explanation:Interference generates false messages and masks legitimate messages. The permanent suspension of a falsely masked message can be prevented by techniques such as positive acknowledgement and timeout.
Q130.
A trace of the path created by stimulus-response event pair is called ____

a.

procedure

b.

sequence

c.

tracer

d.

thread

Discuss
Answer: (d).thread Explanation:Each event might invoke more than one system response. A comprehensive collection of events is called an event-response list. A trace of the path created by stimulus-response event pair is called thread. For example, if caller and respondent are objects, then a trace would contain the caller, handset, MTSO, PTSN, and the respondent.
